Alas, yes. Take two steps backward from it. Think of chapter 2 as "posix on hpss", because that's basically what it is - a client api interface to map all the posix calls into corresponding hpss calls. The first half of the chapter describes the functions and the second half the relevant data structures. The other chapters are gravy - additional kinds of features you can use but wouldn't have to right off the bat, and some of which you'd never use. Funny...I thought there used to be some programming examples in the back, but maybe that was in another book. > Perhaps I should start with User's Guide. I always think of that as just an explanation of the standard user interfaces like ftp and vfs, but you're right, it does talk about some hpss concepts that would be a useful intro. Vicky
